PLOW-JOINTER.

SPECIFICATION forming part of Letters Patent No. 445,281, dated January27, 1891.

Application filed September 24, 1890- Serial No. 365,980. (No model.)

To all whom, it may concern:

Be it known that I, J OHN T. BENDER, a citizen of the United States,residing at Canton, in the county of Stark and State of Ohio, haveinvented certain new and useful Improvements in Plow-Jointers; and I dohereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the annexed drawings,making a part of this specification, and to the letters of referencemarked thereon, in which- Figure l. is a side view of a plow, showing myjointer properly attached thereto. Fig. 2 is a view of the jointer-head,showing the jointer-arms properly attached together, and the mold-boardand jointer-point. Fig. 3 is a detached View of the jointer-head. Fig.4: is a detached view of one of the jointer-arms. Fig. 5 is a detachedview of the jointer moldboard. Fig. 6 is an edge view of thejointerpoint. Fig. 7 is a face view of the jointerpoint. Fig. Sis adetached view of the lower j oin ter-arm.

The present ll 'ention has relation to plowjointers; and it consists inthe different parts and combination of parts hereinafter described, andparticularly pointed out in the claims.

Similar letters of reference indicate corresponding parts in all thefigures of the drawings.

In the accompanying drawings, A represents the jointer-head, which isclamped to a plow-beam by means of the CllllllllllgbOllJS a and thecrossbar Z). The upper jointer-arm I is attached to the jointerl1eadA bymeans of the clamping-bolt c.

For the purpose of adjusting the jointer proper up and down the top orupper end of the jointerarm B is convex, which fits the correspondingconcaved portion of the jointerhead A. The elongated slot 0 is provided,which is for the purpose of allowing the jointer-arm B to be swung backand forth Within the limits of the elongated slot 0, and thereby adjustthe jointer proper up or down and to or from the plow proper. The lowerjointer-arm D is bolted to the upper jointer. arm B by means of theclamping-bolt d, and for the purpose of providing a vertical adjustmentof the jointer proper the elongated slot c is provided. To the lowerportion of the lower jointer-arm D is bolted or otherwise attaehed themold-board E, which moldboard is located as illustrated in Figs. 1 and2. The point F is bolted or otherwise attached to the jointer-arm I)below the moldboard E, and is located substantially as illustrated inFigs. 1 and For the purpose of providing a point having threecutting-points, the point F is made 111 the form of a triangle, therebyproviding the three points f. It will be understood that in use thelower point f will become worn and dull, and thereby unfit for use, atwhich time the point F can be loosened and a new poiutf brought intoposition for use, and so on until the entire three points fare worn out,thus providing in a single point or piece three working-points. Ifdesired, the point F may be formed eonvexo-coneave, the curvature ofsaid point F corresponding substantially with the curvature of themold-board E.

For the purpose of adjusting the jointer proper laterally the elongatedslot 1 is provided.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. The combination of the jointer-head A and means for attaching saidjointer-head to a plow-beam, the arm B, provided with a convex endreceived by a corresponding concaved portion of the jointer-head A, theelongated slot C, the clamping-bolt c, the jointerarm D, ad 3' ustablyattached to the jointer-arm B, the mold-board E, and the point F,substantially as and for the purpose specified.

2. The combination of the head A, the arms 15 and D, and thetriauglepoint F, provided with the pointsf, substantially as and for thepurpose specified.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.

JOHN T. BENDER.
